Qualcomm SLIMbus controller
This controller is used if applications processor driver controls SLIMbus
master component.

Required properties:

 - #address-cells - refer to Documentation/devicetree/bindings/slimbus/bus.txt
 - #size-cells	- refer to Documentation/devicetree/bindings/slimbus/bus.txt

 - reg : Offset and length of the register region(s) for the device
 - reg-names : Register region name(s) referenced in reg above
	 Required register resource entries are:
	 "ctrl": Physical address of controller register blocks
 	 "slew": required for "qcom,apq8064-slim" SOC.
 - compatible : should be "qcom,<SOC-NAME>-slim" for SOC specific compatible
 		followed by "qcom,slim" for fallback.
 - interrupts : Interrupt number used by this controller
 - clocks : Interface and core clocks used by this SLIMbus controller
 - clock-names : Required clock-name entries are:
	"iface" : Interface clock for this controller
	"core" : Interrupt for controller core's BAM

Example:

	slim@28080000 {
		compatible = "qcom,apq8064-slim", "qcom,slim";
		reg = <0x28080000 0x2000>, <0x80207C 4>;
		reg-names = "ctrl", "slew";
		interrupts = <0 33 0>;
		clocks = <&lcc SLIMBUS_SRC>, <&lcc AUDIO_SLIMBUS_CLK>;
		clock-names = "iface", "core";
		#address-cells = <2>;
		#size-cell = <0>;

		wcd9310: audio-codec@1,0{
			compatible = "slim217,60";
			reg = <1 0>;
		};
	};
